APPARATUS FOR PUR lFYl NG WATER BY GALVA NIC ACTION;

SPECIFICATION forming part of Letters Patent No. 649,436, dated November 5, 18.95.

Application filedf'ebruary 15,1895. Serial No- 538,469. (Nomo'deL) To all whom, it may concern:

Be it known that -I, SAMUEL G. CABELL, a citizen of the UnitedStates, residing at Washington, in the District of Columbia, have in vented certain new-and useful Improvements in Apparatus for Purifying Water by Gal-' power and efficiency and be extremely durable in construction.

The invention consists in certain peculiarities in the construction, arrangement, and combination of the several-parts of the apparatus, substantially as hereinafter described, and particularly pointed out in the subjoined claims.

In the accompanying drawings, illustrating the invention, Figure l is a sectional elevation of myim-proved apparatus connected with a boiler and; pump, said apparatus beingdrawn to a larger scale than the boiler and pump.

Fig. 2' is an enlarged horizontal section through thcapparatus; and Fig. 3 is a sectional viewof one of the plates with its peripheral portion broken off. Fig. 4 is a detailed .view of a modified form of plate.

The casing A, within which the water is freed from scale-producing impurities previously to its entrance into the boiler, is con nected at one side with the pump B by the pipe I) and at the other side with the lower end of the boiler G by the pipe 0, (the endof which latterpreferably extends verticallywlthin the casingfifso' as to take the purified water from the upper part of the latter,) and is connected with the upper part of the boiler by the returnpipe 0, said pipes having suitable valves, Wherever necessary, to control the passage of water through them. The casing is provided with a chamber A in its bottom, into which the mud and other heavy'impurities of the water may settle, and said' sediment-collectin g chamber is provided with a blow-01f cook a and with a normally-covered hand-hole, (indicated at 0: through which the sediment may be discharged and removed. The casing is further provided with cocks in its upper end, through which oil may be discharged from the top of the casing when desired, and has a removable cap or cover Afor affording access to its interior.

The construction thus far described" is shown, described, and claimed in my pending application, Serial No. 530,410, filed N overnber 30, 1894, and therefore is not claimed herein, and need not be more particularly described, and, furthermorefmay be varied without afiecting the spirit of the invention, which latter relates entirely to the meansfor producing galvanic action.

lVithin the casing are shown a plurality of plates or partitions D, which divide the easing into chambers and are formed of a metal, such as zinc, which when immersed in water and properly arranged with respect to another suitable metal, such as copper, that is also immersed in the water, produces a galvanic action that frees said water from scale-producing impurities. Each of these. plates has a plurality of projecting knobs,

which maybe tubes d, as shown in Figs. 1

and 2, or made solid, as shown at d, FigQ l. When made tubular, the water flows through them from one chamberinto another in its passage through the casing." These knobs cl are preferably formed integral with and consequently of the same metal as their respective plates. In the construction herein shown the other element of the battery is formed by a lining E of the interior of the casin g and by the rings F F, which latter-serve, also, to

support the plates or partitions intheir proper relative positions, one above another,

and are removably engaged with the same. I

prefer that the plates be of elec'tropositive metal and the lining and rings of electro-* negative metal. The tubes at are preferably arranged in staggered relationship, so that the water will' flow in a circuitous course through the casing, which is of obvious advantage.

It will be observed that the plates are held IOO.

in such relative position by the rings that a water-space is provided above and below each one and that the knobs project from the surfaces of the plates into said water-spaces. By this construction the device will have a maximum power and duration of usefulness and at the same'time may be made very which provides in a small compact structure a maximum amount of surface of metals ca. pable of producing galvanic action, and that therefore the strength and power ofthe apparatus is materially increased, so that it effectually eliminates the scale-producing elements from water rapidly forced through the casing. It will further be seen that plates or partitions constructed as above set forth have a prolonged period of usefulness, as their construction is such as to enable them to withstand corrosive action for a maximum length of time. It will still further be seen that by supporting the pans upon removable rings and providing the casing with a removable cap the elements of the battery maybe quickly assembled and any of them readily removed when necessary or desirable;

\Vhile I herein describe the rings and plates as being formed of relatively electropositive and electronegative metals, respectively, I wishit understood that the rings may be made of electronegative metal and the plates or partitions of a relatively electropositive metal without departing from the spirit of my invention.

Having thus described my invention, what I claim is.- I

1. In an apparatus for purifying water by galvanic action, the combination with the casing having inlet and'outlet ports, .and also having an interior lining forming one battery element, of atube, forming a. water conduit extending longitudinally within the casing and opening near one end thereof, and a series of superimposed perforated plates form- -ing the other battery element, each of said plates having an opening to fit over said tube and being provided with a series of projections, substantially described and for the purposes specified.

2. In an apparatus for purifying water by galvanic action, the combination with the casin g having inlet and outlet ports, and the tube extending longitudinally within said casing and opening near one end thereof, of the perforated plates located one above another within said casing, each of said plates having an opening to fit over said tube-and being provided with a series of projections, and supporting rings alternating with said plates, said rings and plates being formed of relatively electro-positive and negative metals, substantially as described.

In an apparatus for purifying water by galvanic action, the combination with the casing having inlet and outlet ports, the tube forming a water conduit extending longitudi nally within the casing and opening near one end thereof, and the lining for the interior of the casing, of the perforated plates located one above another within said casiii g, each of said plates having an opening through which said'tube ext-ends and being provided with projections, and supporting rings alternatin g with said plates, said lining and rings and the plates being formed of relatively'electropositive and negative metals, substantially as described. v

4. In an apparatus for purifying water, the combination with the casing constructed to permit the ingress and egress of water, of

plates arranged in said casing one above another, each of said plates having a series of tubularprojections, said projections being arranged in staggered relationship to give the water a circuitous course through the casing, and rings alternating with said plates and supporting the same, said rings, plates and projections being formed of relatively electropositive and negative metals, substantially as described.

5. In an apparatus for purifying Water by galvanic action, the combination with the casing constructed to permit the ingress and egress of water, of the series of perforated plates arranged horizontally within said casing oneabove another so as to leave water spaces between their adjacent surfaces, the supporting rings alternating with said plates and encircling said water spaces, and a series of knobs, projecting from the surface of each plate into the adjacent water space to a place considerably below the plane of the top of the adjacent ring, each of said knobs being completely immersed in water, and said rin and plates and knobs being formed of relatively electro positive and negative metals, substantially as described.

111 testimony whereof I affix my signature in presence of two witnesses.
